Question

A smooth sphere is moving on a horizontal surface with velocity vector $$3i^+3j^$$ immediately before it hits a vertical wall. The wall is parallel to $$j^$$ vector and the coefficient of restitution between the sphere and the wall is e $$=$$ $$13$$ The velocity vector of the sphere after it hits the wall is

Infinity Learn · Accepted Answer

velocity perpendicular to the wall becomes $$-ve$$  so x component will change but the y component will remain unchangedso velocity after collision $$-i^$$ $$+$$ $$3j^$$
